Hi guys, never used a digital camera before (hard to believe eh) but I retired and bought X-T100. I only want to take B/W photographs. The large number of menus within menus is confusing me but all I want to do to begin with is to set up the camera to take B/W photos and have the LCD screen showing monochrome also....how do I set it up to do that? Imagine you're talking to a very old 3yo
